Doctrine of Trench Warfare

Hundreds of years of continous fighting, and Oceanyka's experiences with the ANZAC expeditionary force, have created a large pool of skilled trench-diggers, defence works engineers and close quarters fighters. In terrain which cannot sustain armoured offensives, or by substates which cannot afford a mechanised force, the battlefield may revert to combat between opposing fortified structures, usually extremely long trench systems. Continous shelling and reconstruction of defences, commando raids, and bloody frontal assaults characterise this type of fighting.
